CARBURETER.

SPECIFICATION forming part of Letters Patent No. 615,100, dated November 29, 1898.

Application filed March 25, 1898. fierial No. 675,148. (No model.)

To all whom it nuty concern:

Be it known that I, ELIJAH D. PARROTT, of Golden Dale, in the county of Klickitat and State of Washington, have invented a new and Improved Carburetor, of which the following is a full, clear, and exact description.

The invention relates to apparatus for manufacturing gas in which gasolene is evaporated by the use of an air-pump.

The object of the invention is to provide a new and improved apparatus, which is simple and durable in construction, arranged to maintain the same strength of gas throughout the generating process, to consume the gasolene in a uniform manner according to the number of lights in use, to prevent the formation of frost inside of the generating devices, and to prevent freezing of the gasmains between the lights and the carbureter.

The invention consists of novel features and parts and combinations of the same, as will be described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawing, forming a part of this specification and which represents a sectional side elevation of the improvement.

The apparatus is housed in a suitable building A and is provided with a gasolene-storage tank B, provided on its top with a fillingopening B and formed with a false bottom B for producing a gasolene-supply chamber B in the lower part of the storage-tank. A pipe B extends from the chamber B into the lower end of the tank 13, and said pipe is provided at its lower end with a valve B controlled by a float B swimming on the liquid contained in the chamber B By the arrangement described the chamber B receives its supply of gasolene from the tank B, and at the same time a uniform level of the gasolene is maintained in the said chamber by the arrangement of the float B and the valve B controlled from the float.

From the chamber B leads an outlet-pipe 0, controlled from a gasometer, as hereinafter more fully described, for regulating the flow of the gasolene from the chamber B through the pipe 0, according to the amount of gas generated. The lower end of the pipe 0 is connected with a pipe D, containinga valve D and extending through the wall of the building A to a small housing A, arranged on the outside .of the building. The pipe D within the housing A extends downward and opens into a T F, formed on the end of a coil F, arranged within a vessel F located in the building A and set on a drip-can G or other suitable support. The lower end of the coil F terminates in a T F from which leads in a downward direction a pipe F to the said drip-can G, so that any gasolene or other liquid matter not changed into gas in the coil F can float to the drip-can G.

From the upper end of the T F leads a pipe F into an air-pump H of any approved construction and actuated by a drum and weight I or other suitable means. The airpump I-I discharges into a pipe J, which leads to a stand-pipe J, discharging into the gasometer-bell K, mounted in the usual mannor in the gasometer-tank K, supported with- I in the building A.

From the stand-pipe J leads a gas-main L to connect with the humor in which the generated gas is used in the usual manner. From the gas-main L leads a branch pipe L to the housing A, and located within the latter are a valve L and a burner L arranged directly under the T F, which latter is also connected with an air-supply pipe N, extending into the building A and then back again into the hous ing A, and has within the building a regulating-valve N and a check-valve N and in the housing A the pipe N is provided with a hood N located above the burner L and the T F, to receive air heated by the flame issuing from the burner L Now it is evident that by the arrangement described the gasolene can flow through the pipes C and D to the T F and air can pass to the T F in a heated condition from the hood N and pipe N, and as both the air and the gasolene are heated by the said T F it is evident that the gasolene is evaporated and at the same time mixed with the inflowing heated air. The gas flows through the evaporating-coil F to be cooled, preferably by water contained in the tank F As the pump 11 is in motion the gas is readily drawn in by the pump from the coil and forced through the pipe J to the stand-pipe J and to the gasometer, and also to the gasmain L for consumption. The surplus gas accumulates in the gasometer-bell K, which consequently rises in the liquid contained in the gasometer-tank K.

The position of the valve C, that of the "alve N, and of the valve L in the pipe L is regulated by the rising and falling of the bell, and for this purpose the following arrangement is made: The top of the gasometer-bell K is provided with a rod 0, containing adjustable collars 0 0 between which works one end of a lever P, fulcrumed on a bracket I, carried by the gasometer-tank K. The lever P is pivotally connected by a link Q with a lever Q, fulcrumed on a bracket Q carried by the tank B, and the said lever Q, engages a rod R, held to the lever by two nuts R, screwing on the threaded end of the rod and abutting against the top and bottom edges of the lever Q. The rod R extends through a pipe B having a suitable stuffing-box, into the chamber B to connect at its lower end with the arm C of the valve-stem for the valve 0. The lever P is also connected with a link S, having connection with an arm N on the valve-stem of the valve N, and the lower end of the said link S is reduced, as at S, for carryin g adjustable collars S between which operates the arm L on the stem of the valve 1}. Now when the gas accumulates in the gasometer-bell K the latter moves upward, and in doing so imparts a swinging motion to the lever P, which motion is transmitted by the link Q to the lever Q to lift the rod R and shut off the valve C. At the same time the swinging motion of the lever P causes the link S to close the valves l and L and regulate the flow of air to the pipe N and the flow of gas through the pipe L to the burner L Vhen the gasometer-bell K sinks on using the gas stored therein, then the several valves are again proportionately opened to insure generation of gas in the manner previously described, it being understood that the amount of gas generated is regulated according to the number of lights connected with the gas-main L. The several levers P Q and links Q and S have adjustable connections with each other to permit of setting the regulating devices according to the number of lights in use.

The housing A is preferably arranged on the outside of the building to prevent explosions, said housing being provided with a suitable air-inlet A and an air-outlet A If desired, the gasolene may be directly fed from the pipe 0 into the upper portion of the coil F, and for this purpose the valve D is closed and a valve 1) in a branch pipe D is opened, so that the gasolene can flow from the pipe 0 through the branch pipe D into the upper part of the coil F, as will be readily understood by reference to Fig. 2. Normally, however, the valve D is closed, and the valve D is opened for leading the gasolene to the T F to be heated, so as to insure a ready evaporation of the gasolene.

By having the burner L for heating the T F no frost is liable to form inside of the gencrater-coil F, and, if desired, hot air may be sent through the main L to prevent freezing thereof. This is done by closing the valves D and D and heating the air passing from the pipe N into the coil F,the airbeing pumped by the pump I-l through the pipe J into the main L between the lights and the carburetor to prevent freezing of the main.

It will be further understood that by the arrangement described the same strength of gas is maintained throughout the generating process, as the valves for controlling the flow of the gasolene and air are perfectly controlled by the gasometer-bell K.
